SPRINTER W906 CRD3.20 ECU PROBLEM !
#1
Hello members i have problem with sprinter 906 2.2cdi 120kw . 651 engine .
The car does not start and i get a lot of fault codes on the ecu. In the attachment is the photo of the fault codes . I checked all the fuses and the relays are OK .
On the sensors i do NOT get 5V from the ecu . Can the ecu be a problem ?
Thank you .

1. Try to disconnect all sensors connected to 5V bus, 1 by 1.
2. Check wiring short to ground with ECU connectors disconnected.
3. Check power and ground to ECU.
Only after all those steps performed you can say your ECU is the cause.
